Digital Power Conversion with Totem Pole Interleaved PFC

This solution provides a very high-efficiency power supply required by most industrial and telecom equipment. The totem pole PFC eliminates the typical diode bridge used to rectify the AC input, a source of energy loss. Interleaving provides additional efficiency and, finally, a low-ripple DC output. In addition, by combining this with an LLC resonant DC/DC, AC/DC power supply flexibility various applications can be realized.

System Benefits:

• AC/DC power supply with a totem pole interleaved PFC provides high efficiency and low ripple.
• High-efficiency LLC resonant DC/DC can support a wide range of output voltages.
• High-performance MCU with dedicated peripherals for power control and protection to realize high-end algorithms.
• Complete solution which includes the drivers and couplers
